This study evaluates the production behavior and prices in the beef cattle industry in the Brazilian Amazon. We used time series data obtained from various sources and employed multiple regression and polynomial regression analysis. For the price analysis, we used the classical time series model and separated the seasonal and cyclic indices based on the 12-month centered moving average. The analyses covered the period from 1990 to 2015, when the regional cattle population grew at a rate of 5% per year, compared to the national growth rate of 1.7%. The price analysis reveals the existence of cycles in regional cattle ranching, defined mainly by an inverse correlation between the price of fattened cattle and the slaughter of matrices. As for the variables determining the growth of the cattle population, we find that rural credit policy assumes an important role in enabling the supply of resources for financing livestock projects that are more popular than investments in agriculture. The creation and structuring of state agricultural defense agencies in the late 1990s represents an important measure in the institutional sphere, as the implementation of animal health policies and programs has generated a favorable environment for the expansion of investments in meat production and processing, in addition to opening up opportunities for trade in the domestic and international markets.

The objective of this study was to evaluate the technological level and productive performance of the milk producing units of the municipality of Rondon do Pará in the state of Pará. Data were collected through interviews with questionnaires, conducted at 55 dairy farms, which accounted for 43.3% of the milked cows in the municipality. The factors that characterize the systems of bovine milk production were estimated by means of factorial analysis using 12 variables representative of the production units surveyed. Five factors were extracted: F1 = size of the enterprise; F2 = environment and nutrition; F3 = technical assistance and herd management; F4 = animal health; F5 = schooling. From the scores associated with each factor, the index for productive performance of dairy cattle (DFPI) was calculated. The properties were classified into three levels of productive performance, including two considered to have a high level of DFPI, 16 with intermediate productive performance and 37 considered to have a low level of DFPI. There is a need to adopt technologies that promote the productive performance of dairy cattle in Rondon do Pará, as well as enable adaptation to socio-environmental public policies, with the aim of strengthening sustainable rural production through strategic actions that facilitate an increased technological level in farming systems production.

This study describes the bovine milk-producing farms of Rondon do Pará, state of Pará, with the aim of assisting institutional actions and public policies that support the development of the milk production chain. The data were collected from interviews, using questionnaires administered in 55 dairy farms, which together represent 43.3% of the herd of milking cows in the municipality. We collected information on producers, characteristics of the milk-producing farms, dairy exploitation, machines and equipment, facilities and improvements, herd health, milking practices, and herd management. The average age of the interviewees in Rondon do Pará was 57.41 years. The producers had low education levels, with a prevalence of incomplete elementary education. Manual milking was used in 98% of the farms. When it came to hygiene practices, less than 2% of the milkers washed their hands before milk collection, and only 10% cleaned the teats of the cows. Animals were fed almost exclusively on pasture in the rainy season, given that only 2% of the producers complemented the diet with forage. Dairy production involved low technological levels, as the mean productivity was 5.5 L cow -1 day -1. The adoption of technological innovations in herd management may enable the growth and development of the activity in the municipality, and may make producers aware of the principles of sustainability.
